Transcript of an excellent talk by Michael Caulfield. He begins with a historical perspective, first with a description of some of his own projects from the 90s, then a more general account of web history, leading ultimately to MOOCs and open learning. The point of his talk is to question the typical argument for OERs, specifically, that we can create a learning resource once and then reuse it over and over. For practical reasons, this doesn't really work - the 'human core of open', he says, is based on belonging, relevance and diversity of experience. Simply showing a video from Yale won't satisfy these needs. What does resonate, though are what he calls 'choral explanations'. We covered these in July. These support "what we called 'loosely-coupled coursesl — courses that were connected not in this lockstep we-read-everything-on-the-same-day way, but through mutual meaningful activities," he writes. "These loosely-coupled courses did a lot better at engaging connected classes."
